Latest Patents

One of Bruce Wang's latest patents is a device designed to reduce the part count and package size of an in-cylinder ionization detection system. This innovation integrates the ionization detection circuit and ignition coil driver into a single package. The apparatuses aim to lower the cost and complexity of the detection system by combining similar functionalities into one ASIC or electronic module, thereby easing packaging constraints. The device employs a current sink to eliminate noise from voltage spikes, which are high voltage but of short duration. This current sink prevents these spikes from activating the IGBT while allowing the command signal to pass through. Additionally, the device features a switch that multiplexes ionization current and coil primary current.

Another significant aspect of his work is the ignition diagnosis using ionization signal. This subsystem is part of an ignition diagnostics and feedback control system that utilizes ionization current feedback. It monitors various ignition parameters, including primary charge timing, primary charge duration, ignition/spark timing, and ignition/spark duration. This monitoring is crucial for future 'smart' ignition system control. Furthermore, the ionization signal helps detect spark plug carbon fouling and plug insulator overheating, allowing for comprehensive monitoring of each engine cylinder during every engine cycle.
